vBe it knownlthat I, Denim,v VKlU'sTrN Srmnnnn, a citizen. ofthe :UnitedStates,

and residentof Granton, in th'ellcounty of Clark and Stateo'fVVisconsin, have lina vented a certain newand useful Removable Mold forConcrete Walls, yofwhich the fol lowing'is a Specification. Y

This inventlon relates to improvements in molds for forming concrete,walls for buildings, more speciically,to that class of Y moldseprwhichare employed .in building double walls with 'ani air space betweenA them,j and in that class of forms or molds in which the mold members aremoved upwardly as the walls are constructed. In

plates or boards spaced apart a distance equal tothe thickness'of thewall members, and of a depth from oneto two feet; These members arefirstplaced adjacent to the ground surfaceand then filled withconcrete.` After` the concretehas set, .the moldy members are. moved.upwardly withtheirflower edges adjacent Lto the top edge of the wall,thus providing space between lthe members 5 which may again be filledwith concrete.

The plates are usuallyheld imposition relative toeach other-by means ofblocks placed between thermembers and wires to tie them together.,Thisisga very awkward and expensive Way of mounting the4 plates,- and itis therefore the objectvof myl invention tclprovide new and Aimprovedmeansy fori mounting the plates soy they `maybe easily *andvquicklymoved to their new position),vv f c I 'f A rstill furtherObjectis to provide in a movable mold for forming double concrete wallshavingvparallel and horizontallyparranged mold members,improv ed meansfor mounting the mold members sothey may be easilyV and quicklydisengagedfrom ythe walls, and also provide means whereby thesaid'parallel mold members may be 'adjustably mounted relative to eachother.

These and otherobjects will be lapparent to those skilled in the art. ,vy c My invention consists in the construction, arrangement andcombination of the various parts of the device, whereby .thefrfobjectscontemplated arev attained, as hereinafter more fullyset forth, pointedout in my claims, andV illustrated inthe accompanying drawings, inwhich: Y

y Figure 1 is a sideelevation of asegment L of myl improved mold`construction showing the manner in whichit is applied to a wall.

c Fioure 2 is a transverse Sectionalview of the same taken on` the linel2-2 of FigurelL, Y, c V Figure -is a' plan view of one of the moldsupporting frames.

Figure 4. is a detail view form of one of the frame members. Figure 5 isa detail plan view showing the manner in which one of the mold membersis provided with means for forming the upper roof portion of the endwalls of a building.V

of a v*modified Y l have used thelreference numeral 10 to `Y indicatethe walls of a building whichA are mounted parallel to` eachother andspaced apart a slight distance's'o `aste provideja'n air space betweenthem.

The numeral 11V indicates mold platesr which are placed adjacent to theouter edges of each of thewall'members 10 with their lower edgesadjacentto the upper edgel of thefwall membersY 10`so` that the said platesmaybe filled 'between' them :for the purpose f cf'increasing the heightof Vsaid members. ,"Fo'r securing these plates 11 inposition,l'have'provided a series of brackets which arespaced apartatequalintervals Aalongf thel entire length of the wall in whichfpthe'plates extend. T 'Thisf'rame comprises series of vertical members 12placed adjacent to"y the outer face of each of the plates 11,;the` hasaid.` platesV being secured iny position by means of lugs 13 whichextend into dove f tailed groovesfll Ton the inner edge of k'each vofthe' members 12, asclearly shownin Figure 2. l w n' These lugs 13 may beof any desired length, preferably'three 4or four times the width of themember12 so that vthe said members 12 may be attached or detached bysimply moving them longitudinally with. thefmembers 13. n

`The members 12 ,extendy above the upper edgesof the plate aconsiderable distance. Each of the inner me1nbers`12is slightlyyhorizontally 'and transversely arranged glink 15 which is placed aslight ydistance above the rf per edges of the plates 11. rlhe outerVspaced apart and pivotedly connected to a members are each pivotedlyconnected'to the same bar'15 by means of bolts 16 ina-ny one Y .of aseriesof openings 17,sa1d openings being arranged sov that Vthe saidout-ery members 12 Y 18 by means of a may be adjusted. toward or fromthe inner members.

The upper end of each of the members 12 is pivoledly connected to oneend of a lever bolt 19, said bolt being designed to be mounted in anyone of a series of openings 2O in the said lever, the said levers 18being mounted in a substantially horizontal position when the device isapplied to a wall, one of the ,said levers being` arranged to restadjacent to one side of the members 12, while the other lever isdesigned to rest adjacent to the opposite side of said members and thesaid levers eXtended in opposite directions. The outer endy of eachofthe said levers is provided with a handle 21. Y

` Slidably mounted between the inner members 12 and parallel therewith,I have provided a bar 22, the upper end of Vwhichis pivotedly connectedto the central portion of each olthe levers 18. The bar 22 is of alength equal to the inner members 12, and has provided at its lowerend aplate 23 adjacent to each of its sides so as to overlap the inner edgesof the members 12. 'Ihese plates Jform a guide for holding the member 22in proper alinement. Each of the edges not the member 22 ynear its lowerend is formed inclined inwardly until they reach a point beneath theplates 23. The edges then 'are inclined outwardly so that a head 2d isformed on the lower end of said member 22, as clearly shown in dottedvlines in Figure; 2. This head is designed to rest normally adjacent tothe inner'edges of thelower ends of the inner members 12, the

head being of a width equal to the width oic the upper end of the bar22, and when the said head 24 is so spaced the inner members V12 areparallel with each other.

- By moving the handle portion Yof the levers 18 downwardly, it will beseen that thefbar 22V will be moved downwardly which will cause the head24 to be moved i Vdown below the lower endszof the adjacent members 12to a position as shown in eir-v tended dotted lines. This 'will permitthe inner lower corners of the members 12 to rest against the narrowportion of the member 22, said portion being indicated by the numeral25, thus permitting the lower ends of the inner members 12 to swinginwardly about the pivot members in the bar 15, and the inner `plates 11Vto disengageV their respective wall members 10.

This downward movement of the Jfree end or the levers 18 will also.cause [the upper ends of the outer members 12'to be swung inwardly aslightdistance, thereby causing the lower ends of said outer members tobe moved outwardly as the. bars are swung about the bolts 16 and theouter plates 11 to disengagethe outer faces of the walls 10.

The frame members together with the plates 11 may then be easily andquiclrly moved upwardly until their lower edges rest near the upperedges of the wall members, after which the levers 22 are elevated. Thiswill cause the lower ends of the outermembers 12 to move inwardlyr andthe head 24s to be moved upwardly, whichwill cause the lower ends of theinner members 12 to be moved outwardly.r

For locking the upper ends ci? theouter end ot a toggle lever 31, thesaid toggle 23.1

being arranged to lock the plates 27 in position 1n the notches 26, asclearly shown in Figure 2.

f yIhen'it is desired to release the bars 27,

the operator grasps the central portion of the toggle 31 which heelevates and which in turn moves the upper ends of the members 27inwardly until they disengage the notches 26. The levers 22 and the bar18 may then be operated as before described.

Byproviding the openings 20, 17 and 28,

kI have provided means whereby the outer members 12Amay be adjusted toYform walls of di Ierent widths.

`When` the members 12 have been placed outwardly from the positionvshown in Iigure 2 by placing the bolts 16 and 19 into other openings,it--willbe seen that `the upper ends of the members 17 willnot engagethe notches 26, so I have Vprovided openings 28 to permit the bolts 27ato be moved outwardly a distance equal to that in which the members 12are moved outwardly. The boltsBO are then removed andplaced into otheropenings 29 closer to the bolts ,'27n which provides also for theoutward ladjustment or the members 27, and at the Sametime enables thevoperator to use the same toggle member 31. In building foundations, itis often desirable to make one or both of the wall members 10considerably thicker than the wall portion above the foundation. ThisVcan, ol course, be accomplished by adjustingthe bolts before described.When it is desired to build the upper wall narrower than the lower wall,the outer members 12 may be set closer together. f

Inorder to malte anniform offset in the youter face-of either ot thewalls, or both` into a portion 33 parallel with the upper portion 31a,this device being clearly shown in Figure 4. Suitable bent Vplates 34fare substituted for the plates l1. ArIhe bar 31a may be substituted forone of the outer bars l2. After the oii'set portion of thewall has.

been constructed, the outer members 12,1nay be again replaced.

For'fforming the upper edges of the end walls to conform with theslant'of the roof, I have provided openings 35. These lopenings arearranged in inclined rows at each of the members l1. These rows are ofthe same pitch as the root' to be constructed. Each 'of the openings or'the single row is designed toreceive a rod 36 which extends between twomold members used to form each side of the wall, as clearly shown inFigure 5, and. serves the purpose of forming a guide for the mason whenthe concrete is being poured between the said molds. The concrete ispoured so as to aline with the said rods, after which the rods may beremoved when the concrete has set slightly and the said inclined upperedge may then be troweled smooth if so desired.

By this arrangement, it will be seen that'I have provided means wherebythe proper inclination to the upper edge of the roof portion ot thewalls may be easily and quicklyl formed as the concrete may be A pouredbetween the rods.

By this arrangement, it will be seen that I have provided a clamp framefor wall molds which may be easily and quickly applied, and when appliedwill be rigidly held in position, and alsoY which is capable of beingadjusted to walls of different widths.
